MILK AND CREAM TESTER.

Specification of Letters Patent.

Application fi1ed. IiiarchQB, 1914, Serial No. 827,266. Renewed June 19,1916. Serial No. 104,574;

To all whom it may concern Be it known that I, ADoLPH T. HASSINGEB, acitizen of the United States, residing at Greenville, in the county ofOutagamie and State of Wisconsin, have invented certain new and usefulImprovements in Milk and Cream Testers, and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to new and useful improvements in milk and creamtesters, and has for its principal object to provide a device which isarranged to determine by gravity and volume the quantity of butter fatin milk or cream in a reliable and efficient manner.

Another object of the invention is to provide a cream tester which ismade of glass or similar material and. which will not afiect the milk orcream which is being tested and render the same unsalable or unfit foruse. I 1

A further object of the invention is to provide a reliable and eflicientmeans for determining theper cent. of butter fat contained within themilk or cream to eliminate the necessity of sending the milk to atester. With these and other objects in view, the

invention consists in the novel combination and arrangement of-partswhich will be fully set forth in the following specification andaccompanying drawings, in which,

Figure 1 is a longitudinal sectional view of a milk and cream testerconstructed in accordance with'this invention, showing the same in itsassembled position,

Fig. 2 is a side view in elevation of'a portion of the milk and creamtester, and,

Fig. 3 is a view similar to Fig. 2 of the inner portion of the milkandcream tester.

Referring now to the drawings by characters of reference, the numeral 1desig nates the hollow cylinder which is formed of glass or similarmaterial and has formed at its lower extremity the closure 2. The upperend of the cylinder 1 is open as illustrated and is arranged to receivethe milk or cream which is being tested. A suitable line 3 is formedonthe exterior of the cylinder 1 at a spaced distance from the bottom andis arranged to form a gage to indicate the height of the milk incylinder 1, equal in volume to the capacity of cylinder 4 to the pointWhere the tu nlar extension 8 joins the cylinder 1 when the same is tobe put in place.

The inner member which is designated generally by the numeral 4,comprises the hollow cylinder 5 having formed at one end the dome-shapedclosure 6 having the centrally located aperture 7 I formed therein,

and the upwardly extending tubular mem-' inserting the cylinder 4 withinthe cylinder Patented 0ct. 19, 1920. 1

determined weight of the liquid and upon 1, it will be apparent that theliquid will be forced upwardly and it will be apparent since thecylinder 4 is of, the same capacity from-the point where the tubularextension.

joins, to its bottom, as thecylinder 1 contains from the line 8 to itsbottom, the amount of liquid above the line3 on cylinder 1 will beforced upwardly and into the tubular extension 8, to a point even withor near one of the graduations 9 and the user may thus determine byglancing at the graduations and the height of the liquid the quantity orper cent. of butter fat contained therein. In this way it will beevident that considerable time and trouble is eliminated in testingcream and that the same may be used without any danger of contaminationfrom the use of chemicals or similar processes noW llsed.

From the foregoing it will be evident that in use the approximate amountof milk is.

weighed which will fillthe container lto a level with theline 3. Thisweight is then used as a standard and the milk to be tested is thenweighed so as to reach a point either above or below the line 3 withinthe container 1. The richer the milk, the more volume there will be,therefore-it will be seen that the milk will rise to a point above theline 3 within the container 1. Upon the insertion of the container 5, itwill be evident that the milk will rise into the tube 8 so that uponglancing at the graduation,

the percent. of butter fat within the milk may be readily determined. Inevent that the milk from a different source is to be tested, it will bereadily seen that the proper quantity is weighed out and placed in thecontainer 1 and according to the amount of butter fat, it will be seenthat the levelwill riseto a point above or below the line 3, whereuponthe container 5 is then slid in place and the operation repeated. Inthis way it will be evident that various quantities ofmilk fromdiiferentsources may be tested for the amount oi": butter fat and due tothe fact that the greater the butter fat, the greater the volume, itwill be evident that an accurate test of the milk may bemade'whichjwillgive the exact percentage of butter fat. 1

While in the foregoing there has been sho'wnanddescribed the preferredembodiment of-thisinvention, it is to be understood thatsuch changes maybe made in the combinationand arrangement of parts as will fall withinthe. spirit and scope of the invention as defined in the appendedclaims.

Having thus described my. invention, I

claim: V

V 1. Thecombination with a hollow cylinder havinga closure formed atoneend, of a second cylinder adapted to fit within the first cylinjder,said second cylinder being provided with an apertured dome-shaped..closure at its opposite end, and a collarformed integral with theapertured dome shaped closure and projecting upwardly therefrom, saidcollar registering with-the aperture in the dome-shaped closure andbeing provided with graduations to enable the userto easily determinethe quantity of butter fat contained in milk or cream.

2. In a device of the character described,

7 the (combination with a cylinder having a closure atone end, of'asecond cylinder, a dome-shaped closure formed at one end of the secondcylinder, the opposite end of the "in, said cylindrical fextension beingc -lb? vided withia plilrality ofgraduations on its exterior wherebywhen the same is V inserted in the first mentioned cylinder, the liquidcontained insaidcylinder will be forced .intothe tubular extension andthe user may I .determine'by. glancing at the height of the liquid W nth e e o and thqg a ations, the per cent. of butter fat in the milk orcreamwhen the device'is in use.

3. In a device of the kind described, an outervessel open at its top, aninner vessel of smaller cross-sectional area, open at lts bottom, andadapted to be pushed down into the outer vessel to displace liquid fromthe outer vessel into the inner vessel, said outer vessel and innervessel having a liquid tight fit and said inner've'ssel having anextension of relatively small cross-sectional area pro jecting up fromits upper end and into which the liquid isadapted torise,wthe upper endof the extension being open to the atmosphere. r

4. Ina device of the. kind described, an

outer vessel open at its top, an innerdisplacer vessel of smaller.cross-sectional area open at its bottom, and adapted when pushed downinto the outer .vessel to displace liquid fro'mthe outer vessel into theinner vessel, means carried by thelower end of the displacer causing'ittomake afluid tight fit .with.the,outer vessel, said inner vessel havingaclosed top and a tubular extensionthereon of relatlvely smallarea,

a, open at its upper end-and into which the liquid is adapted to rise.

5. In a device of the kind described, an I open topped vcontainenan openbottomed displacer adapted to be pusheddown into the container todisplace liquid from the container into the displacer, means-carriedbythe displacer'for causing all of the-liquid inthe containerto enter thedisplacer, avertical tubular extension on the top of the dis'placer, andscale means associated with said extension for indicating the=rise ofliquid therein. 7

6; In a device of the kinddescribed, a container for holding apredetermined weight of liquid, an open bottomed displacer .of smallercrossrsectional ,areathan the container fitting within the container andadapted to be depressed to displace the liquid from thecontainer intothevdisplacer,
